TWiNE-CAN FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters Patent No. 745,834, dated December 1, 1903.

Application filed September 22, 1902. Serial No. 124,487. (No model.)

To all whom, it may concern:

Be it known that I, PAUL HANSON, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Min nesota, have invented a new and useful Twine-Can for Grain-Binders, of which the following is a specification.

This invention relates to twine-cans for grain-binders.

The object of the invention is to simplify and improve the construction and arrangement of twine-cans for grain-binders and to render the same more efficient in operation.

A further object of the invention is to provide means whereby undue unreeling of the twine from the cop or ball is prevented.

Other objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location, and arrangement of parts, all as will be more fully hereinafter set forth, as shown in the accompanying drawings, and finally pointed out in the appended claims.

Referring to the accompanying drawings, and to the various views and reference-signs appearing thereon, Figure l is a view in side elevation of a construction of twine-can embodying the principles of my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a longitudinal central section. Fig. 4 is a horiaontal section on the line a 4., Fig. 3, looking in the direction of the arrows. Fig. 5 is a View similar to Fig. l,showing a slightly-modified arrangement embraced within the scope of my invention, the upper part of the can being broken ofi. Fig. 6 is a transverse section on the line 6 6, Fig. 5, looking in the direction of the arrows. Fig. 7 is a view similar to Fig. 3, showing the can adapted for use with ordinary Manila twine. Fig. 8 is a detached detail view of the removable coverplate for the opening in the side of the twinecan.

The same part is designated by the same reference-sign wherever it occurs throughout the several views.

In the accompanying drawings, referencesign A designates the can or casing proper provided with a flange-top B, arranged to fit snugly and tightly over the top edge of the can or casing A, whereby it may be readily removed. Suitably secured centrally of the top B is a spout or plug 0, adapted to carry an extra cop or ball of twine, said plug having a longitudinal central bore or opening D therethrough. A sleeve E is arranged to project into the end of the bore D from the inner side of top or cover B to form a hearing. In the bottom or floor F of the canis arranged a step-bearing seat G.

H designates a pin or rod, and in the ends thereof are mounted the dowels or studs J K. The dowel or stud .I is arranged to be received in the bearing-sleeve E, as clearly seen in Fig. 3, while the dowel or stud K is stepped in the bearing-sleeve Gin the bottom or floor F of the can. If desired, and preferably, the step-bearing dowel or stud K may be arranged to rest upon a ball L in order to reduce friction and to enable the pin H to readily and easily revolve. The bearing-sleeves E and G are arranged in alinement with each other and in the geometric center of the top or cover 13 and bottom or floor F of the can. Suitably mounted upon the pin H are the end plates M N. These plates or disks are preferably concaved on their opposed faces, as shown, to conform to the contour of the ends of a cop or ball of twine. These concaved end plates also serve to prevent spreading out of the ball or cop of twine under its own weight, and especially when said cop or ball becomes reduced in size. The upper end plate M is made removable, so as to enable the cop or ball of twine to be placed in position upon the pin H. I

In operation the parts are assembled by applying the end plate N to the end of pin H and then steppingthe dowel-pin K into the bearing-sleeve G. The cop or ball of twine is then slipped over the pin H, and the end plate M is applied to the other end of said pin H. The top or cover B is then applied to the can, with the dowel or stud J received in the bearingsleeve E. Of course it is obvious that the cop or ball may be placed on the pin H while removed from the can, and then the end plates M N applied. and the whole device placed in proper position within the can.

In the operation of a grain-binder in use the twine is reeled 0E from the cop or ball nnevenly-that is to say, variable strains are imposed upon the twine in adirection to reel the same off by reason of the variable movements of the needle, sometimes the twine being pulled off with a jerk. Any violent pull exerted upon the twine tending to unreel the same from the cop or ball imparts rotation to the ball, which under the influence of the momentum of the rotating ball is liable to cause too great a quantity of twine to be reeled off, thereby producing more slack in the twine than is necessary. Moreover, in the initial pull exerted on the twine an undue strain is placed thereon to impart the initial rotative movement to the cop or ball in order to rotate the same from a position of rest. It is among the special purposes of my invention to provide means whereby the twine is yielded evenly and smoothly from the cop or ball under the varying conditions of pull exerted thereon during the operation of the grain-binder in the field and also to provide means whereby an initial rotative movement is imparted to the cop or ball in unreeling and also brake the rotative movement of the cop or ball or to lock the same against rotative movement when the pull on the twine is relieved, so as to prevent undue reeling off of the twine under the momentum of rotative movementimparted to the cop or ball. These objects I accomplish by means of an arm P over a roller or through an eye Q, in the end of which the twine is led from the cop or ball, as clearly indicated in Fig. 2. This arm is preferably bent or curved somewhat to conform to the circular contour of the can and is provided with a stem portion R, suitably journaled in bearings mounted on the outer surface of the can A. A spring S is arranged to exert its tension upon the arm P to yieldingly press the same againstor toward the side of the can. The tension of this spring may be adj ustably regulated in any simple, suitable, or convenient manneras, for instance, by means of a segment-plate T, having teeth, in any one of which the end A of the spring may be engaged. It is obvious that the tension of this spring may be adj usted in any other suitable manner. Mounted upon the stem R is a block B, having a camsurface and arranged to project through a slot or opening in the frame or casing A, so as to be brought into contact with the peripheral surface of disk or plate N. In the particular form shown, but to which my invention is not limited, the plates M N are stamped up out of thin sheet metal, and the plate N is provided with 2. depending flange 0', against which the cam-surface'of block B engages. I do not desire, however, to be limited or restricted to the particular form or construction of disk or plate N emsurface of block B is so relatively arranged as to form a clamp or brake to prevent rotation of disk-N, and hence also 'of the cop or ball, when the arm P is held pressed against or toward the cylindrical casing Athat is, when said arm occupies the position thereof as shown in Fig. 2the tension of spring S exerting a sufficient pressure of the cam-block B against the plate or disk N to arrest and to hold the same against rotation. This camblock also performs the further function of imparting an initial rotative movement to the disk or plate N as the cop or ball whenever the arm P is swung outwardly or away from the canas, for instance, under the pull exerted thereon by the needle of agrain-binder when advancing to its work-thereby relieving the twine itself of the pull necessary to start the cop or ball into rotation.

In Figs. 5 and 6 I have shown a slightlymodified arrangement wherein in addition to the braking efiect of the cam-block B the plate or disk N is positively locked by means of a hook-lever D, mounted upon stem R to rotate therewith, and having its end arranged to be projected or received in one of a series of seats or openings E, formed in the disk or plate N. Thus when the arm P is rocked or swung outwardly or away from the can the hook-lever D is disengaged from the seat or opening E to release the lock, and when the arm P swings in the opposite direction, or toward the can, the hooked end bf lever D enters a seat or opening E and forms a positive lock.

The twine is led from the cop, or ball of twine through an opening G, formed in the side of the can A. In fact, in the particular construction shown an entire panel or section is omitted in the side of the can through which the twine is led to and over the antifriction-roller Q in the end of arm P.

The twine-can above described is particularly well adapted for use with grass twine; 7

but it may sometimes be desired to employ the ordinary Manila twine on the machine, and to avoid the necessity for using separate cans for each machine I provide means whereby the can above described maybe readily adapted for use with Manila twine, and when employed as a holder for the ordinary Manila twine the pin II and its end plates N M are removed and replaced by a removable inner shell or casting H (see Fig. 7) of a sufficient diameter and size to receive the ordinary balls of Manila twine, such as is ordinarily employed for grain-binders purposes, the twine being led from the ball through the bearingsleeve E and bore D of stud G and thence through any ordinary or suitable tension device in the ordinary manner.

It is desirable that a yielding pressure be imposed upon the plate M, tendingto press the same downwardly upon the end of the ball of twine. I have shown a simple means for accomplishing this result, wherein I interpose a spring A between said plate M and a washer B held in pintle J by a pin C In this manner the plate M is yieldingly pressed down upon to closely hug the end of the ball of twine.

If desired, the opening G in the side of the can-bodyA maybe closed in auysuitable manner. In Fig. 8 I have shown a removable cover for said opening. This cover consists of a removable plate or panel D having lugs or flanges E adapted to be turned over to form hooks to engage over the top edges of the can-body and at its lower end provided with lugs F G at each edge thereof, adapted to receive the adjacent edges of the can-body therebetween. This cover plate being of metal can be readily sprung into place or removed when desired.

It is believed that the operation of the apparatus so far described will be readily understood from the description when taken in connection with the accompanying drawings.

It is obvious that many variations and changes in the details of construction and arrangement would readily occur to persons skilled in the art and still fall within the spirit and scope of my invention. I do not desire, therefore, to be limited or restricted to the exact details shown and described; but,
